implants each year and after decades of uncertainty about the safety of those, one new model has women flocking to the doctors' offices with questions. and abc's david wright goes in erch search of answers. >> reporter: in the ongoing quest for perfect breasts, some say it's the holy grail. aubrey has come to dr. grand stevens for a do-over. >> i want gummy bear books. >> reporter: gummy bears. a funny name for a different type of artificial breast. their stevens says gummy bear implants look and feel more like the real thing. >> this is a gummy bear breast implant. >> reporter: more than 300,000 american women a year undergo cosmetic breast surgery. some of them for the second time because the first time she didn't like what she got. >> i want something that felt more natural, this is my body,
and i don't want something fake. >> you want something that's fake, but doesn't feel fake. >> exactly. >> reporter: demand for breast surgery has tripled over the last 15 years. aubrey is among the women who report their new breasts feel unnatural. others report leaking or sagging or hardening. many have to go back for new breasts in fewer than ten years. but according to the doctor, the gummy bears are different. why is this different? >> the gummy bear breast implants are new to americans. they're form stable, they keep their shape. >> reporter: the new implants, approved for use in march are ma -- they are touted as implants too keep their shape even if they're cut in half. >> it's sticky.
>> you can turn it upside down and they're not going to go anywhere. they act like gummy bears. let's call them that. >> reporter: for years, they have been available in the u.s. only to patients willing to take part in a clinical trial through surgeons like dr. stevens. but breast surgery is a sensitive subject. whenever any new product is introduced, there's a really question of safety. there have been problems in the past. there was a moratorium for about 20 years, given concerns that ruptures might increase the risk of r cancer. europe is in the process of a recall from silicone implants. thousands of women are having the implants removed over concerns they tended to rupture.
but the fda says it's confident the newly approved implants are safe. after an eight-year clinical trial. >> so a car accident, direct trauma, right? >> right. >> reporter: he says, they're tougher to rupture. >> this from unscientific experiment, they do seem pretty sturdy. >> it's going to take a lot more trauma than your chest would withstand. >> he swears by the gummy bear, but others say, not so fast. the fda approval of these devices is contingent on follow-up studies to make sure they're safe over time. dr. grth garth fisher says the latest and greatest may not always be the best. you may recognize him from keeping up with the kardashians. >> i love you. >> i know garth fisher is the
